Step-by-step explanation:

Her area of study is too narrow. There are other sources of water in the city that she is not considering. So her sample is too biased leaning toward the Uncle's pond water, and that leaves out every other source. We say that the Uncle's source of water is over-represented while the other sources are completely under-represented.

Let's put it this way: We have a hypothetical city that has 100 acres of pond water either in or surrounding the city limits. If the Uncle's pond only represents 1% of this, then she's ignoring the other 99% of the ponds.

What Lila needs to do to to fix this error is to draw up a map of each major pond and mark those ponds with numbers 001,002,...998,999. In this example, there are 999 ponds. Then she needs to either use a random number table or computer software to help randomly generate values to help select the ponds. Doing so will ensure that she spans a good portion of the city and not stay focused on just the narrow area of her Uncle's backyard.

The reason why she needs to enlarge her area of study is because the results of her Uncle's pond study may lead to the wrong conclusion of the city overall. Let's say his pond is contaminated somehow, and it's only his pond that's the unfortunate one. She would likely see the pond is contaminated and conclude that the whole city's water is ruined as well, which isn't the case. Or we could have nearly the entire city's pond water in trouble, but her Uncle's pond is one of the lucky ponds not to get contaminated. We can see that Lila would likely conclude that no action needs to be taken to clean up the city's water sources, which is also not the case.

If Lila only cared about her Uncle's pond, then that pond (and perhaps immediate close surrounding area) would be her population of study. However, her study is about citywide pond water which is why she needs to extend to other places in the city or in the outer surrounding areas.

The answer to the Question is D

Answer:

B, C, D

Step-by-step explanation:

If the sales price is 15% off, then the the price is .85(100-15%) of the price so c is true

this also makes b true. (100-15%) is p-.15

495 x .85 (100-15%)=420.75 so d is true

Answer:

c. the spinner landing on orange or red

Step-by-step explanation:

So first you find how much is green

25 + 15 + 40 = 80

100 - 80 = 20

So the amount green is 20%

Then you choose the color that has the biggest percentage because it has a higher change of being chosen

25% is red

15% is blue

40% is orange

20% is green

orange and red is the biggest amount/ has the biggest percentage

c is your answer

Answer:

Shown in explanation.

Step-by-step explanation:

These type of problems requires the knowledge of Pythagorean Theorem

Pythagorean Theorem: A^2(shorter side 1)+B^2(shorter side 2)=C^2(Longest side also known as hypotenuse)

So, you would just need to know the square roots of the square.

Triangle 1. First square: [tex]\sqrt{36}[/tex]=6 So side length of first one is 6 yd.

Second square: [tex]\sqrt{18}[/tex]=4.24 So side length of second square is 4.24 yd.

Third square: 36-18=18 So the side length is the same as the second square which is 4.24 yd.

Triangle 2. Repeat the process for all of these problems.

First square: [tex]\sqrt{125}[/tex]=about 11.18.

Second square: [tex]\sqrt{100}[/tex]=10.

Third square: 125-100=25. So, [tex]\sqrt{25}[/tex]=5.

Triangle 3. This is an isosceles triangle meaning 2 sides are the same length.

First and Second square are the same. [tex]\sqrt{32}[/tex]=5.66.

Third square=32+32=64. So, [tex]\sqrt{64}[/tex]=8.

Answer:

It will be 2x -1

If x=2

2*2 - 1 = 4 - 1 = 3

Step-by-step explanation:

7 - x    If x=2

7 - 2 = 5

11 - 3x   If x=2

11 - 3*2 = 11 - 6 = 5

2x -1   If x=2

2*2 - 1 = 4 - 1 = 3

4x - 3    If x=2

4*2 - 3 = 8 - 3 = 5

There are plenty of expressions that will not equal 5, if x is substituted with 2, please be more specific.

Answer: Choice A)  [tex]\cos^{-1} \frac{5}{26}[/tex]

You could also write [tex]\cos^{-1} \left(\frac{5}{26}\right)[/tex] which is the same as writing [tex]\arccos\left(\frac{5}{26}\right)[/tex]

Arccos stands for "arccosine", which is effectively the same as inverse sine. The notation [tex]\cos^{-1}[/tex] means inverse cosine.

We use the cosine rule because

cos(angle) = adjacent/hypotenuse.

isolating the angle leads to

angle = arccos(adjacent/hypotenuse)

We can think of arccosine as an operation to undo the cosine function. It's similar to how division is the opposite of multiplication.

Answer:

132 ft²

Step-by-step explanation:

The shape is composed of a rectangle and a triangle.

Area of the shape = area of rectangle + area of triangle

Area of rectangle = L*W

L = 12 ft

W = 8 ft

Area of rectangle = 12*8 = 96 ft²

Area of triangle = ½bh

b = 8 ft

h = 21 - 12 = 9 ft

Area of triangle = ½(8*9) = 36 ft²

Area of the shape = 96 + 36 = 132 ft²

Answer:

12 square feet

Step-by-step explanation:

A=Area

b=Base

h=Height

To find the area of an triangle, you use the formula A=1/2bh

you plug in the the area and the height to get:

48=1/2xbx8

you do the maths and you get

b=12

Answer:

I believe the answer is 166.6 Joules or (if rounding to the nearest whole number) 167 Joules.

Step-by-step explanation:

Here is the formula to find the gravitational potential energy of an object:

U = m * g * h (potential energy equals mass times gravitational acceleration * the height)

The mass is 8.5 kilograms, the height is 2 meters, and Earth's gravitational acceleration is always, no matter the other values or earthly situations, 9.8 m/s.

Now we solve:

8.5 * 9.8 * 2 = 166.6 which is rounded to 167 Joules.

Step-by-step explanation:

you find the scale factor by using the new shapes number which would be 3 and its corresponding value from the old shape which would be 2

3/2 is equal to 1.5 so thats the scale factor ud need to use

6*1.5 is 9 so thats the answer

Step-by-step explanation:

Number of students = 8

Mean of sample = 876/8

= 109.5

We solve for standard deviation using formula:

S = √(Xi -barX)/n-1

S = 25.3264

A.

H0: u = 100

H1: u not equal to 100

T test = barX - u/s/√n

t = 109.5-100/(25.3264/√8)

= 9.5/8.9542

= 1.0609

Df = 8-1 = 7

P value = 0.953141 at 5% significance level. P-value > 0.05 so we fail to reject H0

Conclusion: insufficient evidence that mean = 100

B.

95% = bar x +-t*s/√n

t = 2.365 at 95% and df = 7

109.5 +- 2.365(25.3264/√8)

= 109.5 +- 2.365(8.9542)

= 109.5-21.1768, 109.5+21.1768

= (88.3232, 130.6768)

In conclusion true mean is in the confidence interval, so it is consistent.
